Stand development is asking for trouble like this. If you must, use semi-stand with agitations every 15 or 20 minutes or so, but you may still get problems with unevenness depending on the film format, developer and reel/tank geometry. It's finicky. It can work OK if everything lines up, but many of us have bumped our heads.
So in short: give it a try with normal agitation, so every minute or so. The problem WILL go away.
